Abstract: Gekko japonicus is a multiple-clutched gecko,with females laying normally two and occasionally one rigid-shelled egg per clutch.No seasonal shifts in clutch mass and egg mass were found in this study,and both variables were positively correlated with maternal size (SVL).Eggs were incubated at five constant temperatures ranging from 24 to 32℃ to assess influence of incubation temperature on eggs and hatchlings.Incubation temperature significantly affected duration of incubation.The average duration of incubation at 24,26,28,30 and 32℃ was 81.4,62.5,52.6,44.7 and 39.5 d,respectively.Hatchlings from eggs incubated at 28℃ were slightly heavier in total dry mass than those from 24 and 26℃,and all other examined hatchling traits (SVL,TL,carcass,residual yolk,fat bodies,head size) did not differ among temperature treatments.Our data reveal that variation in incubation temperature over a wide range does not have important effects on body size and shape of G.japonicus hatchlings.

Key words: Prunus padus, microsatellite loci, spatial autocorrelation analysis, spatial genetic structure.
